I'm away for a couple of days and don't have my camera, nor any images on this device to post at the moment. I'd be happy to do that when I'm back though!

Prior to actually having the lens in my hand, I looked at the flicker images posted under A7/7r with Leica M mount lenses, there are several in there. Also under Voigtlander 21mm f1.8 Ultron. That cinched the image quality for me, but was still worried about size and weight until I went into the shop, subsequently I left with it
